ROTARY VALVE.

Specification of Let ers Patent.

Patented Feb. 3,1914.

Applicadon filed April 7. 191'; Serial No. 759,578.

To all whom it may comm-11.:

Be it known that I, Itnxti (itIiLIJ-JRY, a citizen of the. Frenchlepublic. residing at 103 Avenue de la Republique, Auberrillicrs, Seinein the French Republic, have invented certain new and usefulImprovements in Itotary Valves, of which the following is aspecification.

The present invention relates to a dis tributing system for internalcombustion enchamber and which'comprises therein ports which registerwith the admission and exhaust orifices at theproper times in thedriving cycle.

In order to insure the tightness and also to prevent the pressures (ofcompression or of the explosion of the gaseous mixture) exerted on thedistributor from retarding the sliding of the distributor on the wallsof the cylinder which serve as a valve seat the mechanism which controlsit is such that it maintains the contact: friction between the valve andits seat constant. To this end,

the mechanism connecting the distributor to the controlling member'\\'lil(fl1 transmits to it a continuous movement of rotation about itsaxis, is arranged in such a manner that if the contact motion on thewalls increases there is a relative angular displacement of the drivingand driven members. In consequence thereof and by means of. a suitablemechanical system, the disphn-ement referred to is transformed into alongitudinal displacenn-mt of corres 'iomting amplitude and which, byunscating the distributor. rc-

duces the friction to its normal vahi'c: The

' members then return to their original posisitions which permits ofdriving without any angular displacement the tightness ot thedistributor being then assurot'l owing to the friction existing betweenthe latter and the walls ot the cylinder on vthirh it slides.

The inc-arm, to which the present .int'ention relates porn'iit also ofobtaining the above the system may be.

ivliatcver the. direrti n of rotation' of example: Figure In theaccompanying drawing and by way 1 is a vertical section of the upperpart of a cylinder of a motor comprising a conical distributer to whichare applied the controlling devices embodying the invention. Figs. 2 and3 showin plan two ditl'erent, forms of bearing plates which may becombined with balls so as to form running grooves for them. Figs. 4; and5 are developed views of the bearing plates (Figs. 2, 3) showing theirrelative a-rrangement and their combination with balls and controllingsprings.

The cylinder a ends in a chamber 12 of conical form the walls of whichconstitute the cylinder. Passages 0, (Z for the admission of theexplosive mixture. and the exhaust of the burnt gases to and from thecylinder leadthrough the wall of .the chamber b. The conical chamber 0receives a hollow distributor e, the wall of which is provided with oneor more ports f, and controls the admission and exhaust orifices when itis rotated on its axis. To this end, the distributor e is provided witha vertical spindle g which passes through the cylinder end a; a plate Itis fixed on said shaft and its horizontal surface is provided withgrooves it of different pitch, constituted by any number of cavitieseither spherical Figs. 34)), the radius of which would then be greaterthan that of the balls -i it receives, or oval (Fig. 2). In Fig. 5 theinterposed balls '1'. are shown arranged within similar cavities It ofanother plate j which is arranged above and parallel to the plate 71.keyed on the shaft of the distributor. e. In Fig. lthe plat j is shownprovided with raised surfaces It which co-act with the balls i. Thearrangement shown in Fig. 4 is suitable 't'or engines which alwaysrotate in the same direction. while the arrangemrn't shown in Fig 5 canbe applied to engines which rotate in both directions. This plate j isloosely mounted on. the extension 7.: forming a socket for the cupshaped nut in which closes the chamber It situated above the cylinder u.and receiving the whole of the controlling nteclninism. A ball bearingdisk I pormitsot' the rotation of the plate j on the correspmuling faceof the nut m but opposes the longitudinal displacement; of said plate.The shaft y of the distributor 0 passes freely through the extension A:and is subjected to the action of springs 1 which may be Bellevillewashers or of any other suitable kind arranged on the exterior of.

the motor and within the cup formed by the nut in. The spring p rests,on one hand, on a washer q and aunt 1' of the shaft 9 of thedistributer. e, and, on v the other hand, it rests on a ball bearingdisk 8 pressing on the bottom of the nut m which closes the chamber areceiving the controlling members; in this manner it is possible byscrewing more or less the nut 'r on the shaft 9 of the distributer e toregulate the tension of the spring 79 which presses said distributer onthe wall of the corresponding conical cham-' ber 72' and determines thefriction which insures the tightness of surfaces in contact. The motionis transmitted inany suitable manner from the driving" shaft orsecondary shaft to the engine to a shaft t provided with a worm u, keyedthereon and engaging with the teeth cut on the plate flange j. Theplates h, j, separated by balls 2' which are located and can mbve withinsuitable cavities h h" provided for this purpose, are, moreover,connected by springs 41 which exert a controlling pressure on the partswhen angularly displaced. In Fig. 4:, for example,

,coiled. springs 11: are provided, the ends of which are fixed to ribsin of the plates h, integral 'with the distributerc and the controllingmember, respectively. These springs cact' in tension which is regulatedfor the friction-which, in order to maintain tightness must be of a.sul'licient degree between the distributer and its seat, gives rise to aresisting couple balanced by the couple of said springs o. r

in the modification Fig. fiiblade springs a have been provided, whichare held in position by their ends fitting in between theconjngatedfaces of the plates h, These springs act in a manner exactly like theSPIIYIQ'SU and,moreover, in \VlliltGVBRdlIBG- tion the driving shaft andthe distributer e may be. rotating. It will be seen that, nor mally, thedistributer 0 being pressed on'its scat owingto the spring 1' suitablyregulated" to this end, is driven by the controlling system; the wholeof it rotates without any angular displacement as if the transmissionwere but one element. when thercsistance to the displacement increases,which is due to the friction of the distributor c on its seat increasingthe said distributer tends to retard the driving mechanism whichcontinues to be actuated. The latter acts on the distributer e by meansof its faces It inclined relatively to the faces 71. and the interposedballs 11 so as to free the said (llStlll'llltOl flfim its seat b and todiminish the friction between these members. As soon as the frictiondiminishes, the springs r \vhiclrhave been in tension owing to theangular displacement of the plate 1, 7', of the distributer e and itsdriv- On the contrary, I

ing mechanism, respectively, act on said members in such a manner as toreturn them to their original position. In consequence thereof, thefriction falls to its initial value which is sufficient to maintaintightness but insufficient to produce the seizure of the contactingslidingsurfaces.

The arrangement of the inclined surfaces of varying p tch h, h of theplates h, j between the conjugated faces of which balls i areinterposed, permits of var ing the amplitude of the longitudinal dispacement of the distributer e relatively to its seat b, more rapidly thanthe an les of the an la r displacement between t e said distri uter'andits driving mechanism. In these circumstances, if an angulardisplacement of the distributer e relatively to its drivin mechanismgives rise to a certain longitu lnal dis and tightness.

lVhat I claim as my invention and desire to secure by Letter Itatent ofthe United States is i 1. An internal combustion engine comprising acylinder having a conical chamber at one end, orifices in the wall ofsaid chamber to admit the supply and exhaust of the motive fluid, ahollow and conical distributer in said chamber and sliding on the wallof the latter, orifices in the distributer to control the admission andexhaust ports, a vertical shaft extending from the distributer andhaving athreaded end,a chamber situated' above the distributer, andwhich receives the driving mechanism of the dis tributer, a cup shapednut for closing said chambcr, a hollow boss in the center of said nntprojecting within said chamber b then it will be found that a doubleionand through which passes the shaft of the distributer, a nut adjustablymounted on said shaft, a spring pressing against said nut, which can beshifted on the threaded end of the distributer shaft and against a ballbearing disk at the bottom of the up shaped nut, means for rotating saidistrihnter and maintaining the friction constant between the-distributerand its seat.

2. In an internal combustion engine, a cylinder, the end of whichconstitutes a conical chamber, orifices in the wall of said chamber forthe admissionand exhaust of the motive fluid, a hollow conicaldistributer in said chamber and which has sliding contact With the wallof the latter, orifices in the distributer for controlling the admissionand eX- hanst orifices, a vertical shaft extending from the distrihnterbeyond the distributer and threaded at its upper end, a cup shaped nutsupporting said distributer, a hollow boss in the center of said nut andthrough which passes the shaft of the distributer, a
